Hi, I have a question about the hyperthreading. Previously when I wanted to allocate full node with hyperthreading I did this: #SBATCH --nodes=1 #SBATCH --cpus-per-task=1 #SBATCH --ntasks-per-core=2 #SBATCH --ntasks-per-node=96 #SBATCH --mem=180G This no longer works, i.e., setting ntasks per node to anything higher than 48 will show sbatch: error: Batch job submission failed: Requested node configuration is not available even when the --ntasks-per-core=2 is set. Any ideas? How can I allocate full node with hyperthreading? Best regards Pavel Ondračka
Hi Pavel, due to scheduling issues, which led to not understandable errors, we disabled hyperthreading. Best Marcus Am 07.03.2019 um 09:06 schrieb Pavel Ondračka:

OK, BTW is there some mailing list where should I subscribe to be aware of such changes in the future?
